Abstract:
A method to drive a display with grid array pixels is comprised of writing image data containing a range of grayscale code into multiple pixels; at least a time of a pixel row being divided into frame time and black picture time; each code in the grayscale range being mapped to that in and adjusted range to drive the display without changing gamma voltage or with increased gamma voltage of the greatest grayscale code to present the luminance desired; pixel response time being shorter than frame time; and black picture data being written into the pixel row during the black picture time.
Abstract:
The method increases the output frame rate to p/q (p, q are both natural numbers and p>q) times of the input frame rate. In a period of time equal to the least common multiple of the input and output frame times, q input frames are output and (p−q) transient frames are generated and inserted at appropriate places before or after the q input frames in the output frame sequence so as to enhance the dynamic display effect of the display device.
Abstract:
The present invention discloses an improved LED structure and comprises: a circuit brace, a bowl member; a light chip; a welding line; a packing mask; and a photocatalystic agent. The volume of an LED is smaller so as to be convenient for installment. Compared the present invention to a light tube with same power, the present invention can be added several LEDs in order to increase the curve surface area to contact air, so that the functions of disinfection, deodorization, and mildewproof can be effectively achieved.
Abstract:
A double-frame-rate method for reducing the time lapse of a LCD pixel between its two consecutive scans within a frame is provided. The method horizontally partitions the scan lines into (k) non-overlapping regions, each containing m1, m2, . . . , mk scan lines. The method then scans each of the regions twice before continuing to the next region and, as such, completes two passes of scanning of the entire frame. For a pixel in a region (j), the time lapse between the pixel's two consecutive scans during the frame's frame time is (mj/n) of the time lapse of conventional double-frame-rate methods.
